Novel Binders and Methods for Agglomeration of Ore

Similarly, production of primary iron from iron ore is critically dependent on agglomeration. Concentration of iron oxide minerals requires grinding to very fine particle sizes, frequently smaller than 25 µm, in order to liberate and separate the iron oxides from the silicate gangue.

Iron Ore Agglomeration Technologies IntechOpen

Dec 20, 2017 Fine grained iron ore is pressed into two pockets with the addition of water or some other binder agent (molasses, starch, or tar pitch) to form briquettes . A traditional application is the agglomeration of coal [ 8 ], other example is the agglomeration of ultrafine oxidized dust produced in the ferroalloys industry [ 9 ].

Review of organic binders for iron ore concentrate

May 01, 2014 Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called “pellets.” Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets, but it is
